First-principles simulation of the optical response of bulk and thin-film α-quartz irradiated with an ultrashort intense laser pulse

Kyung-Min Lee, Chul Min Kim, Shunsuke A. Sato +4

A computational method based on a first-principles multiscale simulation has been used for calculating the optical response and the ablation threshold of an optical material irradi…

The importance of Charge Fluctuations for the Topological Phase in SmB

Chul-Hee Min, P. Lutz, S. Fiedler +5

The discovery of topologically non-trivial states in band insulators has induced an extensive search for topological phase in strongly correlated electron systems. In particular, s…

Constraints on composite quark partners from Higgs searches

Thomas Flacke, Jeong Han Kim, Seung J. Lee +1

In composite Higgs models, the generation of quark masses requires the standard model-like quarks to be partially or fully composite states which are accompanied by composite quark…

Kaon Condensation in Neutron Stars with Skyrme-Hartree-Fock Models

Yeunhwan Lim, Kyujin Kwak, Chang Ho Hyun +1

We investigate nuclear matter equations of state in neutron star with kaon condensation. It is generally known that the existence of kaons in neutron star makes the equation of sta…

Cosmologically probing ultra-light particle dark matter using 21 cm signals

Kenji Kadota, Yi Mao, Kiyomoto Ichiki +1

There can arise ubiquitous ultra-light scalar fields in the Universe, such as the pseudo-Goldstone bosons from the spontaneous breaking of an approximate symmetry, which can make a…

Magnon breakdown in a two dimensional triangular lattice Heisenberg antiferromagnet of multiferroic LuMnO

Joosung Oh, Manh Duc Le, Jaehong Jeong +7

The breakdown of magnons, the quasiparticles of magnetic systems, has rarely been seen. By using an inelastic neutron scattering technique we report the observation of spontaneous…
